Answer:
G 6.231 and 6.233
Step-by-step explanation:
F 6.232 and 6.236 rounds to 6.23, 6.24
G 6.231 and 6.233 rounds to 6.23, 6.23
H 6.229 and 6.239 rounds to 6.23, 6.24
J 6.222 and 6.238 rounds to 6.22, 6.24
_____
One way to determine the rounded value is to add 0.005 to the number, then drop all digits to the right of the hundredths place.
<u>Examples</u>:
6.222 +0.005 = 6.227 ⇒ 6.22
6.238 +0.005 = 6.243 ⇒ 6.24
Because x,y,z form a geometric sequence, therefore the common ratio is
r = y/x = z/y
That is,
y² = xz (1)
We are given:
x + y + z = 18
Therefore
x + z = 18 - y (2)
Also,
x² + y² + z² = 612
Therefore, from (1), obtain
x² + z² + xz = 612
(x + z)² - xz = 612
From (1) and (2), obtain
(18 - y)² - y² = 612
324 - 36y + y² - y² = 612
-36y = 288
y = -8
Answer: y = -8
The area is 14 because the triangles area is 6 and the rectangles area is 8
<span>B. 3/7, 18/42
This work, because you multiply 6 top and bottom
